Public bug reported:
When switching users, sound does not work for the new user. Messages are
seen in the system log like this:
Aug 20 17:29:31 localhost pulseaudio[19234]: pid.c: Daemon already
running.
Aug 20 17:29:31 localhost pulseaudio[18979]: x11wrap.c: XOpenDisplay()
failed
Aug 20 17:29:31 localhost pulseaudio[18979]: module.c: Failed to load
module "module-x11-publish" (argument: "display=:0.0"): initialization failed.
It seems likely related to http://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=593746. I don't think all the information
presented there is currently relevant - or the workaround effective - as
the start-pulseaudio-x11 script isn't used to start pulseaudio and it
does use autospawn on Ubuntu. My current workaround is to start a new
pulseaudio for the second user (without killing the old one).
